Except for compliance with the applicable provisions of Sections 13 and 16 of the Exchange Act, the consummation by Shareholder of the transactions contemplated hereby will not violate, or require any consent, approval, or notice under, any provision of any judgment, order, decree, statute, law, rule or regulation applicable to Shareholder.

SECTION 4. Transfer of the Shares.

Prior to the termination of this Agreement, except as otherwise provided herein, Shareholder shall not: (a) transfer, assign, sell, gift-over, pledge or otherwise dispose of, or consent to any of the foregoing (“Transfer”), any or all of the Shares or any right or interest therein; (b) enter into any contract, option or other agreement, arrangement or understanding with respect to any Transfer; (c) grant any proxy, power-of-attorney or other authorization or consent with respect to any of the Shares; (d) deposit any of the Shares into a voting trust, or enter into a voting agreement or arrangement with respect to any of the Shares; (e) exercise, or give notice of an intent to exercise, any Options unless the Shares underlying such Options become subject to this Agreement upon such Option exercise; or (f) take any other action, other than in Shareholder’s capacity as an officer or director of the Company, that would in any way restrict, limit or interfere with the performance of Shareholder’s obligations hereunder or the transactions contemplated hereby.

SECTION 5. Grant of Irrevocable Proxy; Appointment of Proxy.

(a) Shareholder hereby irrevocably grants to, and appoints, Parent and any designee thereof, Shareholder’s proxy and attorney-in-fact (with full power of substitution), for and in the name, place and stead of Shareholder, to vote the Shares, or to grant a consent or approval in respect of the Shares, in connection with any meeting of the shareholders of the Company or any action by written consent in lieu of a meeting of shareholders of the Company (i) in favor of the Merger or any other transaction pursuant to which Parent or Merger Sub proposes to acquire the Company, whether by tender offer, merger, or otherwise, in which shareholders of the Company would receive consideration per share of Common Stock equal to or greater than the consideration to be received by such shareholders in the Offer and the Merger, and/or (ii) against any action or agreement which would impede, interfere with or prevent the Merger, including, but not limited to, any other extraordinary corporate transaction, including a merger, acquisition, sale, consolidation, reorganization or liquidation involving the Company and a third party, or any other proposal of a third party to acquire the Company.

(b) Shareholder represents that any proxies heretofore given in respect of the Shares, if any, are revocable, and hereby revokes any such proxies.

(c) Shareholder hereby affirms that the irrevocable proxy set forth in this Section 5 is given in connection with the execution of the Merger Agreement, and that such irrevocable proxy is given to secure the performance of the duties of Shareholder under this Agreement. Shareholder hereby further affirms that the irrevocable proxy is coupled with an interest and, except as set forth in Section 7 hereof, is intended to be irrevocable in accordance with the provisions of Section 1759 of the Pennsylvania Business Corporation Law. If for any reason the proxy granted herein is not irrevocable, then Shareholder agrees to vote Shareholder’s Shares as instructed by Parent in writing.

SECTION 6. Acquisition Proposals; Non-Solicitation.

or assist or participate in, or facilitate or take any action that could reasonably be expected to facilitate, any such inquiries, proposals, offers, discussions or negotiations; provided, however, that nothing herein shall prevent Shareholder from acting in his or her capacity as an officer or director of the Company, or taking any action in such capacity (including at the direction of the Company Board), but only in either such case as and to the extent permitted by Section 5.02(b) of the Merger Agreement. Shareholder shall immediately cease participating in any solicitation, discussion or negotiation with any Person with respect to any actual or potential Acquisition Transaction.

This Agreement shall terminate, and neither Parent nor Shareholder shall have any rights or obligations hereunder and this Agreement shall become null and void and have no effect upon the earlier to occur of (i) the Effective Time and (ii) the date of termination of the Merger Agreement in accordance with its terms; provided, however, that termination of this Agreement shall not prevent any party hereunder from seeking any remedies (at law or in equity) against any other party hereto for such party’s breach of any of the terms of this Agreement. Notwithstanding the foregoing, Sections 8(a), 8(e), 8(f), 8(j), 8(k), 8(l), and 8(n) of this Agreement shall survive the termination of this Agreement.

The failure of any party hereto to exercise any right, power or remedy provided under this Agreement or otherwise available in respect hereof at law or in equity, or to insist upon compliance by any other party hereto with its obligations hereunder, and any custom or practice of the parties at variance with the terms hereof shall not constitute a waiver by such party of its right to exercise any such or other right, power or remedy or to demand such compliance.

It is accordingly agreed that until such time as this Agreement is validly terminated pursuant to the provisions of Section 7, the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in the United States District Court for the District of Delaware or any other competent court of the State of Delaware (collectively, the “Delaware Courts”), this being in addition to any other remedy to which they are entitled at law or in equity.

(g) Entire Agreement.

(h) Assignment. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned, in whole or in part, by operation of law or otherwise by any of the parties without the prior written consent of the other parties, and any assignment without such consent shall be null and void; provided, however, that Merger Sub may assign, in its sole and absolute discretion, any or all of its rights, interests and obligations under this Agreement to Parent or any direct or indirect wholly owned Subsidiary of Parent. No assignment (including an assignment to which the Company has consented) shall release Parent of its obligations hereunder. Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of, and be enforceable by, the parties and their respective successors and assigns.

(i) Parties in Interest. This Agreement shall be binding upon and inure solely to the benefit of each party hereto and their respective successors and permitted assigns, and nothing in this Agreement, express or implied, is intended to and does not confer upon any Person other than the parties any legal or equitable rights or remedies, whether as third party beneficiaries or otherwise.

(j) Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF DELAWARE, REGARDLESS OF THE LAWS THAT MIGHT OTHERWISE GOVERN UNDER APPLICABLE PRINCIPLES OF CONFLICTS OF LAWS (WHETHER OF THE STATE OF DELAWARE OR ANY OTHER JURISDICTION) THAT WOULD CAUSE THE APPLICATION OF THE LAWS OF ANY STATE OTHER THAN THE STATE OF DELAWARE, EXCEPT TO THE EXTENT THAT MANDATORY PROVISIONS OF THE BUSINESS CORPORATION LAW ARE APPLICABLE HERETO.

(k) Consent to Jurisdiction. Each of the parties hereto hereby (i) irrevocably and unconditionally submits, for itself and its property, to the exclusive jurisdiction of the Delaware Courts in any action or proceeding arising out of or relating to this Agreement or the agreements delivered in connection herewith or the transactions contemplated hereby or thereby or for recognition or enforcement of any judgment relating thereto, (ii) agrees that it will not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any Delaware Court, (iii) agrees that it will not bring any such action or proceeding in any court other than the Delaware Courts, (iv) agrees that any Claim in respect of any such action or proceeding may be heard and determined in any Delaware Court, (v) waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any such action or proceeding in any Delaware Court and (vi) waives, to the fullest extent it may legally and effectively do so, the defense of an inconvenient forum to the maintenance of such action or proceeding in any Delaware Court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law. Each party to this Agreement irrevocably consents to service of process in the manner provided

for notices in Section 8(a). Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by Law.

(l) Waiver of Jury Trial. EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE IT HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT AND ANY OF THE AGREEMENTS DELIVERED IN CONNECTION HEREWITH OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (I) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE EITHER OF SUCH WAIVERS, (II) IT UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF SUCH WAIVERS, (III) IT MAKES SUCH WAIVERS VOLUNTARILY, AND (IV) IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 8(l).

(n) Action in Shareholder Capacity Only. Parent and Merger Sub acknowledge that Shareholder has entered into this Agreement solely in its capacity as the record and/or beneficial owner of the Shares and not in any capacity as a director or officer of the Company. Nothing herein shall limit or affect any actions taken by Shareholder or its Affiliates or designee, or require Shareholder or its Affiliates or designee to take any action, in each case, in his or her capacity as a director or officer of the Company, and any actions taken, or failure to take any actions, by such a director or officer in such capacity shall not be deemed to constitute a breach of this Agreement (it being understood that the matters that are the subject of Section 6 hereof are subject to Section 5.02 of the Merger Agreement as it relates to such director or officer in his or her capacity as such).
